Hello everyone,I am a rookie in OpenFOAM and I try to simulate a stratified two-phase flow in a rectangular channel (slice), a pretty easy setup 0.99 x 0.131 x 0.001 m3 where there water is up to the height of 0.031m, the sides in the z-direction are symmetryPlanes, while the top and the bottom of the channel are walls. The fluids are entering the domain in x direction both with the same velocity.The BC’s are:inletWater (x<=0.99 && y<=0.031 && z<=0.001):alpha1-fixedValue uniform 1; epsilon - fixedValue uniform 0.04996; k - fixedValue uniform 0.003; p-zeroGradient; U-fixedValue (0.28 0 0)

OpenFoam stops with following error: #1 Foam::sigFpe::sigFpeHandler(int) in "/opt/products/farm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"#2 ?? in "/lib/libc.so.6"#3 Foam::Time::adjustDeltaT() in "/opt/products/farm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"#4 main in "/opt/products/farm/OpenFOAM/OpenFOAM-1.6/applications/bin/linux64GccDPOpt/interFoam"#5 __libc_start_main in "/lib/libc.so.6"#6 Foam::regIOobject::writeObject(Foam::IOstream::str eamFormat, Foam::IOstream::versionNumber, Foam::IOstream::compressionType) const in "/opt/products/farm/OpenFOAM/OpenFOAM-1.6/applications/bin/linux64GccDPOpt/interFoam"

Hope you can help me,
Thanks!

PROBLEM SOLVED: The initial velocities of the two phases where to high. Slowly increasing the inlet values did the trick!
